It is my understanding the JSR will be filed fairly soon, but that's a bit of conjecture based on conversations I've had with Ed. I can't really say with any certainty when that will be, but I got the impression that it shouldn't be too much longer.

Pre-JCP-filed draft for JavaServer Faces 2.0 JSR
Posted by: Joseph Ottinger on March 30, 2007 DIGG
Ed Burns has posted a reference to the proposal for JSF 2.0 on his blog.
The proposal focuses on ease of development (no config XML files), the use of templates, bookmarkable urls, and many more elements, including REST and AJAX usage in JSF. They're also focusing on ease of deployment, meaning that components should be "hot-deployable."....
This is aimed at Java EE 6, so it's likely to be quite some time - the initial proposal suggests March of 2008.
